Cheap interface NO FLASH CARDS NO QUIZZES     Garbage MusicLovr204

Helped me cheat on my chemistry quiz thanks                     AWESOME Helperrr

For the users that complained it was simply a list and not like flashcards I say this scroll down A simple swipe will reveal the formula name of the ion Simple app but useful                 Flashcard Ions Kyle Johnston

Totally useless I thought this would be like a flashcard format but it simply names a bunch of polyatomics It doesn t even match the names with the formulas     Not immediately useful daggerjehu

Really helpful on my midterm                     Perfect for my Chem 101 class King Jubba

I like how it is simple to use and you can scroll down to find the answer I did catch a mistake on acetate It is actually CH3 COO                     Ions Chazwa12

This is not a good app I hate chemistry enough already Please make something better I cannot fail I want to go to college         Make better apps D.holt

This is a great app It has helped me so much with my homework I highly recommend it and it s free                     Exactly what I need Cool Beanz!

Works just like I wanted it too I use it almost every day in chem                     Great thatkaykay

Nice simple study aid Dissapointed to see advertisement bar but would still recommend download for a free app                 Good OlrikV

Ok so I got this app hoping it would help me in chem Boy I was wrong It gives you all the names of ions and symbols but there is no order whatsoever You have to know all the ions 100 in order to like this app Big waste of time     Bad app joshv9

I used this as a supplement for chemistry studying and it s great I haven t had time to make flashcards and this really helps with the polyatomics                 Works for me Trannyboy

It took me a couple seconds to figure out I had to scroll down to see the formula for the given name or vice versa no tapping or anything Other than that it s does exactly what it says saves you time from making flash cards I ve only used it for about 20 minutes so far but I haven t had any glitches                     Good app for free michele9

This app is ok but I don t really recommend this for studying unless you want a free app First off it s kinda of a pain to go back and fourth the way it s set up There needs to be a next button of some sort Or even better there needs to be a button that randomizes the ions to better suit it for studying Another thing I don t like is something that you can see in the screen shots which is when I select an ion let s say Ammonium it takes me to another screen that says Ammonium Ok as if I don t remember what I hit a second ago It needs to show the symbol and charge right away instead of me having to scroll down the page to view it The advertisement bar is kind of annoying where it s located at top wish it was at the bottom As it stands in the current version I would not recommend this app for studying It s just not set up well for that purpose I m currently in a chemistry class and knowing all of the ions is a must I am having better success with an app called Polyatomics which is better suited for studying but it cost a dollar         A very basic app Aaxel21

good                     good cd17822
